Waterflooding: Performance Predictions and Surveillance (RES28)

Description

Waterflooding is one of the most commonly implemented improved oil recovery techniques in the world. In this course the participants are presented the fundamental concepts of oil displacement by water and provided techniques for estimating recovery, evaluating behaviour and monitoring performance of waterflood projects.

This 5-day course covers the reservoir engineering aspects of waterflooding in clastic and carbonate reservoirs. The seminar combines geology, rock and fluid properties, and immiscible displacement theory to develop waterflooding prediction techniques and to aid in the evaluation of actual waterflood performance behaviour. Detailed predictions of oil and water producing rates, water injection rates and recovery efficiency are presented. Selection of waterflood patterns (regular, irregular, peripheral), prediction of sweep efficiency (areal, vertical and displacement), and an analysis of other variables which control recovery efficiency are included. Also discussed are waterflood surveillance techniques such as production testing, production plots (rate-time, rate-cum, WOR-cum, etc.), VRR analysis, volumetric sweep (reservoir conformance) determination, injection profile testing, pressure transient testing, step-rate testing, Hall plots (pros and cons), pattern balancing, bubble maps, and injection efficiency determination. These surveillance techniques provide the engineer with data required for the efficient management of both new and mature waterfloods. The course content and example problems have been selected to teach and illustrate important concepts.

Course Level: SkillInstructor: Michael L. Wiggins

Designed for you, if you are...

An engineer or geologist at just about any experience level, from no waterflood experience to several years of waterflood experience

The course is presented in a manner so that both beginners and experienced personnel will find the material very useful. The course content and example problems have been selected to teach and illustrate important concepts.

How we build your confidence

Theoretical concepts are clearly explained and examples used to demonstrate oil displacement by water. The concepts are presented individually; so you will have a complete understanding of displacement principles and how they affect oil recovery when designing or analysing a waterflood project.
